Water purifier system with natural fiber and activated charcoal for Rasbora lateristriata spawning

Poor water quality is characterized when used for bathing with foamy water, contains solvents and deposits, emits odors, non-neutral acidity, excess microorganisms, changes in water temperature and colored water. The purpose of this water treatment is to remove most of the suspended solids and dissolved materials. Several processes that can be applied in this water treatment include the separation of coagulants and neutralization through contact with palm fiber as a natural fiber, activated carbon, silica, and zeolite materials. In this study, the prototype Water Purifier system (WP system) has been tested in the form of a tube to separate concentrated river water through the designed channel. The parameterized Total Dissolved Solid (TDS) quality, pH and mercury content have good values for the quality of water for spawning with a value of 1.6 ppb. The water purifier arrangement can reduce the maximum mercury (Hg) value by 17.2%, where the value is only 0.6 ppb above the standard that has been used.
